摘　　要：近年来倍受关注的α-亚麻酸,能够替代鱼油中的二十碳五烯酸和二十二碳六烯酸对人体发挥重要的保健作用。而亚麻是理想的α-亚麻酸来源,亚麻子中α-亚麻酸含量高达50%∽60%。环境因素（如温度、降水量等）和遗传因素对亚麻子中α-亚麻酸积累的影响极为显著。本研究根据α-亚麻酸1968-2014年的研究成果,对α-亚麻酸的保健功能、α-亚麻酸的积累规律、影响α-亚麻酸合成的环境因素和α-亚麻酸合成的相关基因调控等方面进行了简要概述。The α-linolenic acid which has been paid attention in recent years, plays an important role on human health as the alternative of the EPA and DHA from fish oil. The flaxseed oil is the best source of α--linolenic acid with 50% -60% in content. Environmental factors （such as temperature and precipitation intensity） and genetic factors may have a significant impact on α-linolenic acid accumulation in flaxseed. In this paper, healthy function, accumulation mechanism, environmental factors and gene regulation of the α-linolenic acid was discussed on flax.
